Answer:

Value of A = 10

Step-by-step explanation:

Here Isoke is solving the quadratic equation by completing the square

        10x² + 40x – 13 = 0

         10x² + 40x – 13 + 13 = 0 + 13

         10x² + 40x + 0 = 13

         10x² + 40x = 13

          10 ( x² + 4x) = 13

   Here it is given as

           A(x² + 4x) = 13  

Comparing both

           We will get A = 10

Value of A = 10

ehidna [41]

Answer:

5 months

Step-by-step explanation:

Given :The bank withdraws $15  from Betsy’s checking account as a  service fee every month.

To Find :  Betsy has budgeted $75 for  the next few service fees. For how many  months will the service fee be covered?

Solution :

So. $1 is service fee for month = \frac{1}{15}

So, $75 is service fee for months = \frac{75}{15}

                                                       = 5

Hence$75 service charge will be covered for 5 months .

Can someone please help me with my hw 20 points?
Neporo4naja [7]

Answer:

The first equation; x-2y=8

Step-by-step explanation:

Hi there!

We're told that Ty wants to isolate x in one of the equations. To do so in either, he will need to use inverse operations to cancel out values and leave just x remaining on one side of the equation.

In the second equation, he would need to subtract both sides by 6y and then divide both sides by 4 to isolate x. It's a two-step process.

However, in the first equation, he only needs to add 2y to both sides to isolate x.

I hope this helps!
